Abstract. Volatile organic compounds (VOCs) are key precursors of ozone and particulate matter, which the two dominant air pollutants in urban environments. However, compositions sources VOCs aloft have rarely been reported so far. To address this highly time-resolved measurements were made by a proton-transfer-reaction time-of-flight mass spectrometer (PTR-ToF-MS) at 450 m platform on Canton Tower Guangzhou, China. A combination situ modeling techniques was used to characterize variations...
Negligible losses were observed for many atmospheric trace species after traversing the PFA Teflon tubing that was hundreds of meters in length.
With the rapid development of aviation industry, number airborne electronic devices is gradually increasing, and mismatch between heat dissipation power supply demand has become a major problem that needs to be solved urgently. Among many cooling technologies, phase change storage exchange scheme better performance can solve complex thermal management problems caused by long-term high-power operation short-term high flux impact during aircraft flight. Based on numerical simulation...
The deformation of frozen soil under impact loading is usually accompanied by the evolution internal defects and microdamage. By taking strain rates into account, a rate-dependent damage law proposed in this study, assumption equivalent strain. Subsequently, damage-modified constitutive model to describe dynamic mechanical properties soil. A split Hopkinson pressure bar utilized test response at different temperatures high rates. experimental results show that produces obvious rate...
To reveal the influences of soil particle size on dynamic impact mechanical properties frozen soil, four groups specimens composed different sizes are tested using a split-Hopkinson pressure bar. Based Druger–Prager failure criterion and coupled damage-plasticity, micro-constitutive model is established for describing behavior soil. Macroscopically, assumed to be homogeneous continuous, although large number micro-cracks micro-voids distributed randomly throughout volume. When specimen...
In this study, an electrochemical sensor for the real-time monitoring of propofol (PPF) in anesthesia was developed using molecularly imprinted polymers and reduced graphene oxide-modified glassy carbon electrodes (MIPs/rGO/GCE). To make electrode, GO thermally into rGO, which then electrodeposited on GCE (rGO/GCE), followed by electropolymerization MIPs LiClO4, pyrrole, PPF (template) solution rGO/GCE The taken out pyrrole polymer. X-ray Diffraction (XRD), Scanning Electron Microscopy...
Ballast systems and ballast water dynamic allocation between tanks are very important for ensuring the offshore operation efficiency safety of revolving floating crane (RFC). Its modeling solving have multiple difficulties such as complexity, complexity engineering practicability. Early studies showed that domain knowledge is great significance optimization design quality innovation complex issues. By analyzing coupled process characteristics among crane, ship hull system, a model based on...
Abstract The navigation safety of polar ships depends on accurate monitoring ice conditions along the route. Complex environments but scarce datasets pose challenges for deep learning‐based object detection methods. To address this issue, we propose an method based environment adaptive image enhancement. This approach adaptively augments dataset by simulating such as snowflakes and aurora to improve training precision models in harsh meet needs safe ships. First, augmentation randomly...
